Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538926, here are decompositions:
- 137 + 31538789 = 31538926
- 173 + 31538753 = 31538926
- 197 + 31538729 = 31538926
- 233 + 31538693 = 31538926
- 347 + 31538579 = 31538926
- 449 + 31538477 = 31538926
- 593 + 31538333 = 31538926
- 599 + 31538327 = 31538926
Showing the first eight; more decompositions exist.
